K but don't forget, they're heading down south. that's where Jace would be. Unless you stalk them from a distance.... oO
And as a head's up, the only way you're going to know he's a hybrid is because depending on the extremity of his mood, he'd change color. Far as you know, he's stealing a car. You may follow him down south with the others. To make it interesting, really possibly let him lose you within the city and then you'd stick around and run into him again or something.
Just a thought.
